Do Tears Dilute Your Pain? was a post I had several people commented that tears cleansed the body of certain chemicals. Not one to leave a topic alone here’s some excerpts from an article that I found interesting.

The Health Benefits of Crying
Emotional or stress-related tears are thought to help us through difficult times in a number of ways.
“. . . research has suggested that tears could actually be a way of flushing negative chemicals out of the body and doing you a world of good. We look at why it’s good to cry.
A study by Dr William H. Frey II, a biochemist at the St Paul-Ramsey Medical Centre in Minnesota, found that there is an important chemical difference between emotional or stress-related tears and those simply caused by physical irritants – such as when cutting onions.”
“They found that emotional tears contained more of the protein-based hormones prolactin, adrenocorticotropic hormone, and leucine enkephalin (a natural painkiller), all of which are produced by our body when under stress.”
“We all need the layer of protective fluid covering our eyeballs known as continuous or basal tears.
Basal tears contain lysozyme, a powerful and fast acting antibacterial and anti-viral agent. Without this, the eye – because it’s a moist environment – would suffer enormous amounts of bacterial attack and you could potentially go blind.”
“One of the most important functions crying can have is to protect our eyes from irritants and foreign bodies, such as dust or getting rid of the acidic fumes when cutting onions.
These tears are known as reflex tears. When our eyes come under attack from irritants, the lachrymal glands in our eyes start stimulating more fluid to wash away the irritant and drain it from the eye.
Physically, they are thought to wash toxic chemicals out of our bodies, while psychologically giving your feelings a good airing is thought to be a healthy tonic.”
“Crying is thought to help reduce stress, which can have a damaging effect on our health and has been linked to a number of health problems including heart disease, high blood pressure, type-2 diabetes and obesity.
According to the Minnesota study, crying can help to wash chemicals linked to stress out of our body, one of the reasons we feel much better after a good cry. Higher levels of adrenocorticotrophic (ACTH) have been found in emotional tears (compared to reflex tears).
Removing this chemical from the body is beneficial because it triggers cortisol, the stress hormone – too much of which can lead to health problems associated with stress.
‘When you’re upset and stressed, you have an imbalance and build up of chemicals in the body and crying helps to reduce that.'”
Dealing with sorrow
“Aside from removing toxic substances from our body, crying can also have the psychological benefit of lifting our mood and helping us to deal with painful situations.
Deep crying is generally felt to be good for you in that it exposes and expresses deep emotions, which means they can then be dealt with.
‘Whether crying is good for you depends a lot on the reasons for it, the context, and how it is handled.
Crying can also signal a need for help from others and bring people together. People are usually more likely to help someone when they see them dissolve into tears, and it can prompt helpful behaviour.
It may also be a signal for physical contact, such as a hug or reassuring hand placed on an arm – and touch has been linked with helping stress reduction”.
Too many tears
“However, frequent crying is not always good for you and can be a sign of more serious conditions, such as depression, post-traumatic stress disorder and postnatal depression.
What’s more, the healing affect of crying won’t work for everyone. Researchers have discovered that people who suffer a mood disorder are less likely to feel better after crying. If you’re depressed and crying all the time, it’s not good and you might need help,’ says Dr Abigael San.”
“88.8 per cent of people feel better after crying, with 8.4 per cent feeling worse.
On average women cry 47 times a year and men a mere seven.
Until puberty, crying levels are much the same for each gender – testosterone may reduce crying in boys while oestrogen and prolactin increases the tendency in girls.
Men may excrete more of the toxins related to emotional stress in their sweat because they have higher sweat levels than women.”
